    Answer:1350 joules

    Explanation; the formular for kinetic energy is 1/2mass * velocity^2

    So : 1/2*75*6^2=2700/2

    Which is 1350 joules

    Answer: KE = 1350 J

    Explanation: Kinetic Energy is expressed in the following equation:

    KE = 1/2 mv²

    Substitute the values

    KE = 1/2 (75kg) (6m/s) ²

    = 1350 J
